About four days after the events of the first film, former assassin John Wick tracks down his stolen 1969 Ford Mustang Mach 1 at a chop shop owned by Abram Tarasov, brother of Viggo and uncle of Iosef. John dispatches Tarasov's men in a violent fight that heavily damages his car. He then spares Tarasov under the auspices of peace and returns home.

After Aurelio takes John's Mustang for repairs, John is visited by Italian crime lord Santino D'Antonio. It is revealed that to complete his "impossible task"—which allowed him to retire and marry Helen—John asked D'Antonio for help. As a form of contract, D'Antonio swore John to a "Marker", an unbreakable promise symbolized by a "blood oath" medallion. D'Antonio presents the medallion to demand services from John, but John refuses, claiming that he is "retired". In retaliation, D'Antonio destroys John's house with a grenade launcher.

Winston, the owner of the Continental hotel in New York City, reminds John that if he rejects the Marker, he will be violating one of the two unbreakable rules of the underworld: no killing on Continental grounds, and Markers must be honored. John accepts his commitment and meets with D'Antonio, who tasks him with assassinating his sister Gianna D'Antonio so he can claim her seat on the "High Table", a council of high-level crime lords. D'Antonio sends Ares, his personal bodyguard, to follow and keep an eye on John.

Similar to the first, generally a weak story line but action packed with gory fights that appealed more to the male audiences. Not forgetting more of a fan fad hence the higher rating in general. Well, I do know the fans are truly happy since Chapter 3 is in the making.

It was just something to watch when there's nothing much in the movies for me. At some point, it definitely looked so unrealistic on how it was plotted for the casts to be killed or how they could be easily swayed to die or how John was indestructible even when he was rained with so many bullets! Unbelievably unrealistic... nuff said.
